Description

IPCS spectra centered on 6200 A at 6.7 A dispersion have been obtained for four giant stars 47 Tuc-L5427, M71-AH78, M71-AH77, and Arcturus. An abundance analysis relative to Arcturus gives values of Fe/H equals -0.4 and -0.75 for M71 and 47 Tuc, respectively, and near solar-like ratios of Ti, V, and Zr relative to Fe. Reanalysis of the coolest star AH77 with a higher temperature and lowered continuum gives an Fe abundance and Ti/Fe ratio reminiscent of some recent echelle-derived abundance analyses
